Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of wiring harness connection fixation, specifically relates to a wiring harness connection fixing device. BACKGROUND

[0002] Wiring harness is commonly used for signal and circuit transmission, such as automobile wiring harness and switchboard wiring harness. The existing Chinese patent application No. CN210350262U proposes a wiring harness connection fixing device, which connects the connector and the plug-in piece together by setting the bolt and the screw hole, thereby effectively ensuring the stability of the connection between the two, achieving the purpose of not loosening when subjected to external force. However, the above-mentioned device still has certain defects: although the threaded connection method ensures the stability of the connection between the two, it is relatively cumbersome in the process of installation and disassembly, which is not conducive to the maintenance and replacement of the aging or damaged connector in the subsequent process. To solve the above-mentioned problems, the Chinese patent application No. CN220021817U also proposes a wiring harness connection fixing device, which is connected and positioned by a spring. When the plug-in piece is inserted into the connector, it can be self-locked under the limiting action of the ball, and the separation of the ball and the plug-in block is realized by the driving end, thereby achieving the purpose of stable connection and quick disassembly, which is convenient for subsequent maintenance and replacement of the connector. However, the ball is connected and positioned by the elastic element (spring), and when the connector and the plug-in piece are subjected to a large pulling force, the plug-in block will pull the ball, which may cause the ball to pull the elastic element (spring), which may cause the elastic element (spring) to be pulled and deformed, ultimately leading to the failure of the self-locking structure of the connector and the plug-in piece. At the same time, the driving end needs to be powered, and after long-term use, the power failure will cause the driving end to fail, and the structure cost is relatively high.
